Everything is revealed by knowing, and the Self is revealed by everything; because their nature is one, knowing and the known are contemplated as one.

Commentary
Singh: 'knowing' here stands for the knower; the known is revealed by the knower and the knower by the known. He cites the Ucchuṣmabhairava ('so long as there are no knowers, how can there be the known?') and a verse quoted by Śivopādhyāya: manifestation is not separate from the light of consciousness, nor that light from I-consciousness. Contemplating subject, object and consciousness as one reality, one attains Bhairava's nature. Singh classes it as śāktopāya. Singh reports a second reading, per Lakshmanjoo: 'knowledge reveals things in the world and the Self is the source of all revelation; since they are not different, the knower is revealed in knowledge'. Wallis's translation follows that reading.
How to sit with it
Look at, or listen to, anything. Notice that it is revealed by your knowing, and that your knowing is revealed by it. Let the two be seen as one nature, one knowing, and rest there.
Where attention rests
The knower and the known, each revealing the other
Their single shared nature: knowing
Not a body shape. The map is the knower and the known as two faces of one knowing, each revealing the other.
Breath
Natural breath. Count about four in and four out only if it helps you settle, then let the count go. No forced hold.
The counts are an optional school pacing aid, not part of the verse. Hold is always 0: this school never adds a deliberate breath-hold.
Any steady, comfortable position (school addition)
Any steady, comfortable position: sitting on a chair, sitting on the floor with support under the hips, or lying on the back. Standing or walking slowly is also acceptable when that is easier. Choose the position in which the body needs the least effort.
School addition. Verse 137 does not specify a body position. The seat is a convenience so the dharana can be practised; it is not part of the technique and makes no claim of tradition.
Safety
Pain is information. Pause, regress, or exit. Never push through sharp pain.
General practice caution only; not medical advice. If this becomes abstract, simply rest in plain seeing or hearing. If anything feels distressing (dizziness, agitation, strong emotion), stop, open the eyes and rest attention on the feet and the floor.
This door needs no particular posture: sit on a chair, sit on the floor with support, or lie down. Eyes may stay open.
Honesty
Door 112 follows Vijñāna Bhairava Tantra dharana 112 (verse 137) in Jaideva Singh's numbering. The door-to-dharana index is a School of 112 Doorways teaching device. Singh's sequence is one edition's count, not an ancient one-to-one canon. The seat, counts, reaction and beat scripts are school additions.
Door index = Jaideva Singh dharana number: Door 112 is dharana 112, verse 137. Other editions number differently (see dharana.numbering_variants).
The seat, breath counts, reaction metaphor, attention-map drawing and beat scripts are school devices, not part of the verse.
The English is a school paraphrase, not a quotation from any translator.
No medical claims. Reaction names are metaphors, not biochemistry.
New door researched on 2026-10-06 on branch research/vbt-houses-2-7; awaiting guardian review.
Name the door. This is Door 112: knower and known as one. Vijñāna Bhairava Tantra dharana 112, verse 137.
Geometry. No shape to make. Sit with the eyes open or closed. The map is the knower and the known as one knowing.
Orientation. Let the floor or the chair carry you. Eyes closed or soft.
Breath. Natural breath. Count about four in and four out only if it helps. No forced hold.
Attention. Look at anything. It is revealed by your knowing; your knowing is revealed by it. One nature. Rest there.
Reaction cue. School image: two arcs closing into one circle. A metaphor, not medicine.
Adiyogi thread. Verse 137: everything is revealed by knowing, and the Self by everything; because their nature is one, knower and known are contemplated as one.
Exit / integrate. Let the practice go. Take one free breath. Open the eyes and look around the room.
